I also have a sample of L'Air du Desert Marocain which l haven't tried yet.

Thank you for pointing this one to my attention! This sample is a challenge for me, as I remember from testing it, and I did not even considered it to be an amber (on me it was death by cumin). So today in the spirit of making an SnS a bit of a challenge, I got this one out and managed the tiniest dabs on my skin. Yes, small application makes wonders sometimes. I get some warmth from the spices, but not a cumin overdose.

Speak up, people, anyone here SPRAYS this stuff?
(and yes, do you spray Ambre Sultan too?) this one I am also doing in tiny dabs right now maybe, I'll graduate from preschool one fine day

Sure do! I happily spray both of them ... although I usually save LdDM for days off of work.

Maybe some day I will too. Right now I actually dab all of them, because all my ambers are in dab samples. I love them all! But some I do generous dabs, and other still scare me off

Ambre Fetiche has a kick ass opening of some strong incense (Mr. W. suggested that right out of the vial it smelled like turpentine!), then it dried to a nice amber, and now every time I breathe on my arm I get a funny note of toasted nuts or sunflower seeds! Not what I would've expected from an amber, nice, nevertheless. Certainly different.

I continued with Profumi del Forte Versilia Vintage Ambra Mediterranea. Boy, this is a no-nonsense amber! It's very serious, maybe even dark. I remember it a happier one when I wore it on a beautiful August evening. I bet my skin was a lot warmer on that day!
